Rename events:
- domain-feature-set -> domain-feature-set:feature
- domain-feature-delete -> domain-feature-delete:feature
- domain-tag-add -> domain-tag-add:tag
- domain-tag-delete -> domain-tag-delete:tag
Make it consistent with property-* events. It makes more sense to
include tag/feature name in event name, so handler can watch a single
tag/feature - which is the most common case. Otherwise, most handlers
would begin with `if feature == '...'` anyway, wasting time on most
events.
In cases where multiple features/tags should be handled by a single
handler, it is now possible to register a handler with wildcard, for
example `domain-feature-set:*`.
Support registering handlers for more flexible wildcard events: not only
'*', but also 'something*'. This allows to register handlers for
'property-set:*' and such.
Load integration tests from outside of core-admin repository, through
entry points.
Create wrapper for VM object to keep very basic compatibility with tests
written for core2. This means if test use only basic functionality
(vm.start(), vm.run()), the same test will work for both core2 and
core3. This is especially important for app-* repositories, where the
same version serves multiple Qubes branches.
This also hides asyncio usage from tests writer.
See QubesOS/qubes-issues#1800 for details on original feature.
Test base functions of dom0 module (creating VM, setting property) and
configuring system inside of VM (through DispVM). The later is done for
each available template (the process use salt installed in that
template, not copied from dom0).
QubesOS/qubes-issues#3316
When dom0 do not provide the kernel, it should also not set kernel
command line in libvirt config. Otherwise qemu in stubdom fails to start
because it get -append option without -kernel, which is illegal
configuration.
FixesQubesOS/qubes-issues#3339
Add property for IPv6 address ('ip6'). Build default value similarly to
IPv4 - common prefix + QID or Disp ID (for DispVMs).
This all is disabled unless 'ipv6' feature is enabled. It is inherited
from netvm (not template).
Even when enabled, VM may decide to not use it - or simply not support
it.
QubesOS/qubes-issues#718
Allow using default feature value from netvm, not template. This makes
sense for network-related features like using tor, supporting ipv6 etc.
Similarly to check_with_template, expose it also on Admin API.
Having both default_netvm and default_fw_netvm cause a lot of confusion,
because it isn't clear for the user which one is used when. Additionally
changing provides_network property may also change netvm property, which
may be unintended effect. This as a whole make it hard to:
- cover all netvm-changing actions with policy for Admin API
- cover all netvm-changing events (for example to apply the change to
the running VM, or to check for netvm loops)
As suggested by @qubesuser, kill the default_fw_netvm property and
simplify the logic around it.
Since we're past rc1, implement also migration logic. And add tests for
said migration.

* qubesos/pr/166:
create "lvm" pool using rootfs thin pool instead of hardcoding qubes_dom0-pool00
change default pool code to be fast
cache PropertyHolder.property_list and use O(1) property name lookups
remove unused netid code
cache isinstance(default, collections.Callable)
don't access netvm if it's None in visible_gateway/netmask
There were many cases were the check was missing:
- changing default_netvm
- resetting netvm to default value
- loading already broken qubes.xml
Since it was possible to create broken qubes.xml using legal calls, do
not reject loading such file, instead break the loop(s) by setting netvm
to None when loop is detected. This will be also useful if still not all
places are covered...
Place the check in default_netvm setter. Skip it during qubes.xml loading
(when events_enabled=False), but still keep it in setter, to _validate_ the
value before any property-* event got fired.

xterm is very fast on closing when application inside terminates. It is
so fast with closing on keydown event that xdotool do not manage to send
keyup event, resulting in xdotool crash. Add a little more time for
that.
Besides converting itself, change how the test verify restore
correctness: first collect VM metadata (and hashes of data) into plain
dict, then compare against it. This allow to destroy old VMs objects
before restoring the backup, so avoid having duplicate objects of the
same VM - which results in weird effects like trying to undefine libvirt
object twice.
This one pool/volume property makes sense to change dynamically. There
may be more such properties, but lets be on the safe side and take
whitelist approach - allow only selected (just one for now), instead of
blacklisting any harmful ones.
QubesOS/qubes-issues#3256
Do not check for accepted value only in constructor, do that in property
setter. This will allow enforcing the limit regardless of how the value
was set.
This is preparation for dynamic revisions_to_keep change.
QubesOS/qubes-issues#3256
The previous version did not ensure that the stopped/shutdown event was
handled before a new VM start. This can easily lead to problems like in
QubesOS/qubes-issues#3164.
This improved version now ensures that the stopped/shutdown events are
handled before a new VM start.
Additionally this version should be more robust against unreliable
events from libvirt. It handles missing, duplicated and delayed stopped
events.
Instead of one 'domain-shutdown' event there are now 'domain-stopped'
and 'domain-shutdown'. The later is generated after the former. This way
it's easy to run code after the VM is shutdown including the stop of
it's storage.
If domain got removed during the tests (for example DispVM), vm.close()
wouldn't be called in cleanup and some file descriptors will be
leaked. Add event handler for cleaning this up. Do not use close()
method here, because it is destructive, but the object may still be used
by the test.
Allow to get default value even it isn't set currently. This will allow
(G)UI to present better view, without duplicating logic for default
value.
FixesQubesOS/qubes-issues#3197
Check resize on each template separately, because it involves VM's
scripts (either qubes.ResizeDisk service, or some startup script).
QubesOS/qubes-issues#3173
- clone all features, not just qrexec (especially include 'gui')
- do not leak VM reference on failed test
- add test for online root volume resize

Expired rules are skipped while loading the firewall. Do that also when
such rules expired after loading the firewall. This applies to both
Admin API and actually applying the rules (sending them to appropriate
VM).

This is a race condition, so to make it more likely to fail (if it's
broken), make some things manually. In normal circumstances this order
of actions is also possible, just less likely to happen. But as seen in
the bug report, happens from time to time.

vm.create_qdb_entries can be called multiple times - for example when
changing VM IP. Move starting qdb watcher to start(). And just in case,
cleanup old watcher (if still exists) before starting new one.
This fixes one FD leak.
Do not use self.fail when handling exception - this will keep exception
object referenced, which in turn have reference to domain object (via
traceback).
- Prefer instance attributes over local variables - the former ones do
not leak into traceback object and are cleaned up by tests framework.
- Use 'with' syntax for handling files.
- Use subprocess.DEVNULL instead of open('/dev/null') where applicable
- Delete local variables when not needed anymore.
- Fix str/bytes
- Call skipTest as early as possible - before doing any setup
- Fix networking tests - configuration commands needs to be called as
root (missing user= argument).
- Fix setting firewall - policy is no longer changeable
- Add missing loop.run_until_complete() calls.
- Convert subprocess.Popen to asyncio.create_subprocess_exec where
needed (when called process needs to communicate with qubesd).
- Cleanup processes (call .wait()).
There is no more significant difference between PV and HVM. VMs are HVM
by default anyway. More important for this test is difference between
Linux (with Qubes packages installed) and other OS-es. Rename tests
accordingly. The later one is still incomplete.
The most important change is doing vm.close() when removing domain -
this means it wouldn't be cleaned later by iterating over app.domains.
Other changes include removing VMs in the right order, regarding netvm
dependency (otherwise killing or removing may fail). And one more
missing coroutine handling (in shutdown_and_wait).
There is intentionally no default template in terms of qubes.property
definition, to not cause problems when switching global default_template
property - like breaking some VMs, or forcing the user to shutdown all
of them for this. But this also means it shouldn't be allowed to reset
template to "default" value, because it will result in a VM without
template at all.

FixesQubesOS/qubes-issues#3047
Clone properties from DispVM template after setting base properties
(qid, name, uuid). This means we can use standard clone_properties()
function. Otherwise various setters may fail - for example
netvm setter require uuid property initialized (for VM lookup in VM
collection).
Also, make dispvm_allowed check more robust - include direct creation of
DispVM, and also check just before VM startup (if property was changed
in the meantime).

qvm-sync-clock in dom0 now synchronize only dom0 time. For VM time,
qvm-sync-clock needs to be called in VM. Also, both will communicate
with qubesd, so must be called asynchronously from tests.
Allow attached device to be converted from persistent to non-persistent
and the other way around.
This is to allow starting a VM with some device attached temporarily.
When VM is not running, it is possible to attach device only
persistently, so this change will allow to do that, then, after starting
the VM, change it to non-persistent - so it will not be attached again
at further startups.
QubesOS/qubes-issues#3055
This is because .tearDown() is not executed if the exception occurs in
setUp() [for example self.skipTest() raises an exception]. The lower
levels of .tearDown() being executed are critical to not leaking file
descriptors.
